[Opsoclonus-myoclonus syndrome in children with neuroblastoma: description of 3 cases].

Neuroblastoma (NBL) is one of the most common childhood malignancies. Presence of untypical symptoms is characteristic for this malignancy; therefore it may mimic many other illnesses, both malignant and nonmalignant. Particular attention should be focused on opsoclonus-myoclonus syndrome (OMS, Kinsbourne's syndrome).

[Implementation of the unified model of presenting cancer diagnosis in Polish pediatric onco-hematology centers].

Presentation of full information related to diagnosis of children with cancer should be one of principles in pediatric oncology. Multidisciplinary approach to each newly diagnosed child and its parents contributes to improving this standard. The Polish Pediatric Leukemia and Lymphoma Group is engaged in these activities since 1998 and it resulted in implementation of several SIOP recommendations in most of Polish pediatric oncohematology centers.

[Implementation of a psychological support program for children with cancer in Poland. Preliminary report].

Intensive chemotherapy programme in children with cancer may result in psychological mal adjustment. Treatment facilities as well as psychological support are of great importance to minimize these side effects. In 1998 the programme of psychological support was introduced in 7 Polish paediatric haematology / oncology centres.

[Comparative evaluation of visual acuity after cataract extraction with monofocal, bifocal or progressive lenses implantation].

Purpose: Evaluation which of the lenses: monofocal, bifocal or progressive, assure the best visual acuity in patients.

Material And Methods: 86 patients aged from 21 to 84 years were operated. Monofocal lenses were implanted in 30 cases, bifocal in 32 and progressive in 24 cases.

[Comparative evaluation of corneal endothelial cells after extracapsular cataract extraction with PMMA and heparin-surface modified lens implantation].

Purpose: Comparison of endothelial cells density in eyes after PMMA and heparin-surface-modified lenses (HSfM1) implantation.

Material And Methods: 58 patients (26 male and 32 female) aged from 36 to 89 years. In 30 patients PMMA lenses produced by Pharmacia, Storz and Alcon and in 28 HSM (Pharmacia) lenses were implanted, after ECCE.

[Evaluation of 200 extracapsular cataract extractions using the envelope technique].

Purpose: To present own results of extracapsular cataract extraction with the use of the envelope technique.

Material: 200 patients (110 male, 87 female and 3 children) aged from 7 to 86 years operated in the Department of Ophthalmology in Bydgoszcz from December 1992 to May 1996, including patients with congenital, senile, presenile cataract or with diabetes.

Results: In 187 patients (93.

[Methods of coping with the disease and treatment in children with neoplastic blood diseases].

Neoplastic disease and the employed therapeutic management may cause strong anxiety in children. The authors analyzed factors affecting anxiety level. The analysis included the reaction of children to hospitalization and methods of coping with diseases and therapy by children in various age groups.

[Corneal endothelium after cataract surgery].

Corneal endothelium was examined in 95 patients with a contact endothelial specular microscope before endothelium was examined in 95 patients before and after extracapsular cataract extraction with IOL implantation. The patients were divided into four groups, depending on the surgical techniques: I--traditional can opener capsulectomy with lens implanted in ciliary sulcus, II--envelope technique, III--envelope technique preceded by laser anterior capsulotomy, IV--phacoemulsification. In the last 3 groups the IOL was placed in the lens capsule.

[Corneal endothelium after radical keratotomy].

Corneal endothelium was examined in 37 patients with a contact endothelial specular microscope before and after radial keratotomy. The mean percent of cell loss was 0.9% one month and 2.

[Artificial intraocular lenses in patients with cataracts and glaucoma].

The authors evaluated 52 glaucomatous eyes in which, after the extracapsular cataract extraction, artificial posterior lens has been implanted. In 32 patients glaucoma has been treated for 2-6 years. In 7 patients of this group, it was not possible to control the intraocular pressure before surgery and in these cases simultaneous trabeculectomy, extracapsular cataract extraction and the implantation of artificial posterior lens were performed.

[Use of transconjunctival cryoapplication in chronic pars planitis with involvement of peripheral retina and choroid].

The transconjunctival cryoapplication was performed in 8 patients (13 eyes) with the recurrent pars planitis and the simultaneous involvement of peripheral retina and choroid. Before the surgery, the peripheral fundus of the eye was examined with the Goldmann three-mirror lens and afterwards, the cryoapplication of lesions was performed. The topical treatment, dexamethasone and indomethacin drops, followed the surgery only.

[Late results of the treatment of eye burns].

An analysis of patients treated in the Ophthalmic Department in Bydgoszcz for eye burns in the 10 years period from 1980 till 1990. Taken into account were the causes of burns, the treatment installed in the early period and in cases of late complications. All the patients were asked to call in for a control examination in order to compare the condition of the eyes at the date of discharge and in the long-lasting time.

[Critical evaluation of the treatment of diabetic retinopathy based on personal experience].

The authors present the results of analysis of the treatment of 184 patients (360 eyes) with diabetic retinopathy; it comprises as well the out-patients as the in-patients divided into 4 groups in dependence on the changes and the treatment applied (laser focused photocoagulation, panretinal photocoagulation, cryopexy) the majority of patients reported to the hospital with an advanced proliferative diabetic retinopathy and this allowed only the performance of a panretinal photocoagulation and in a part of cases only cryopexy. The attention is called to the necessity of an early detection of pathological changes and of an early treatment.

[Preoperative anterior capsulotomy using YAG laser in cataract extraction by the envelope method. Preliminary report].

The envelope technique was used in 50 patients with cataract. In 25 patients anterior capsulotomy was performed by YAG laser before surgery (in 5 persons 1 day, in the remaining 20 1 hour before operation). The sole complications connected with laser capsulotomy was the raise in the intraocular pressure in 2 patients.

[Study of the fundus oculi periphery in patients with posterior- chamber lenses].

Evaluation of the eye fundus after an extracapsular cataract extraction with posterior chamber lens implantation was performed in 50 patients 1 month after surgery and in 50 another patients 2 years after surgery. In the earlier period a very good inspection was possible in 88 p.c.

[Intraocular lenses in patients with diabetes mellitus].

Presented are personal experiences concerning the application of artificial intraocular lenses in patients with diabetes and cataract. Operated were patients aged 50-76 years in whom implantation of an artificial lens of Alcon or Cilco was performed either to the anterior or posterior chamber. During the qualification for surgery eliminated were patients with proliferating retinopathy, with rubeosis iridis (with or without secondary glaucoma) and with juvenile diabetes.
